Identification of Key Nodes in Complex Power Grid Based on Electrical Distance

分析网络特性与连锁故障所传递的特征对大范围停电事故的影响。通过电网分布机理深入研究和分析经典网络模型中无法结合并判断网络潮流的分布规律,在此基础之上分析电网参数中所包含的物理信息。按照叠加原理计算出电网阶段距离,总结和归纳网络节点中的电气耦合连接度,揭示出电网内部异质结构。

The impact of grid characteristics and cascading failures on large-scale blackouts is analyzed.By in-depth study and analysis of the distribution mechanism of power grid,the distribution law of power flow can not be combined and judged in the classical grid model.On this basis,the physical information contained in the parameters of power grid is analyzed.According to the principle of superposition,the phase distance of power grid is calculated,the electrical coupling connectivity of grid nodes is summarized and summarized,and the internal heterogeneous structure of power grid is revealed.
